STREET-INDICATOR FOR CARS.

cater. for Cars, of which the following is a specification.

My invention relates to street indicators, and more particularly .tostreet indicators carried upon cars for the purpose of disclosing, topersons occupying the cars, the names of the streets, in successiveorder, as the car travels along.

More particularly stated, my invention comprehends an indicator having aband or ribbon upon which the names of the streets are successivelydisplayed, and improved mechanism for actuating this ribbon or band stepby step.

My invention further comprehcnds means for enabling the indicatingmechanism to automatically make allowance for streets, the names of:which are not intended to be displayed, the indicator mechanism being soarranged that when a car passes a street, the name of which is not to bedisplayed, such name will he practically skipped, though the name inquestion may be carried by the ribbon or band.

My invention further contemplates mccha nisn'i for automaticallyreversing the direction of step by step travel oi. the indicatingmechai'iism whenever the car reaches'the end ot the route and startsupon its return trip.

My invention also.com 'irchemls mechanism for enabling the name ribbonto be virtually lengthened or shortened in order to adapt'thc apparatusas a whole for scrv ice upon either long or short routes with aminimum-of time and trouble to the operator.

invention comprises, in addition, a

' number of improvements for incrmising the etii'ciency of indicatormechanisms of the class to which this one relates.

Other objects sought to be accomplished by my invention will appear asl'iereinatter described, and in connection with the detaileddescription. v

Fig.9 is a detail showing a switch used in connection with the mechanism forcausing the street names to be practically skipped. Fig. 10 shows agroup f electric switch mechanisms used for the purpose of automaticallyshifting the various circuits during, the operation of the indicatormechanism. Fig. 11 is a side elevation showing a form of indicatormechanism in which provision is inade'for lengthening or shorteningthename ribbon. Fig. 12 is :1 diagram of the wiring. Fig. 13 is afragmentary section on the line lit-'13 of Fig. 2, looking in thedirection of the arrow.

The indicator casing is shown at 13 and is provided with a Window 14through which legends indicating the street designations may beobserved. Secured to the casing is a framework 15 for supporting variousparts. Two drums are shown at 16, 17, and connected with these drums aregear wheels 18, 19. The drums and gear wheels are mounted rigidly upontwohorizontally dis.- poscd shafts 20, 21, the latter being journaled Arelatively to the framework.

Mounted rigidly-upon the shaft 21 is a wheel 22 provided with radiallydisposed stop pins 23. Two sprocket chains 24, 25, are mounted upon thegear wheels 18, 19, and are located in plai'ies' 'iarallel to each Iother. Guiderollers 26 are disposed adjapass certain parts withoutdisturbing them,

as hereinafter described.

Another arm 29 is mounted upon the chain 24, but is shorter than the arm28. Both of these arms, together with an arm 30 shown in dotted lines inFig. l, and substantially similar to the arm 28, are used for thepurpose of tripping certain switch levers as described below.

Mounted within the casing 13 are two solenoids 31, 32, disposed in axialalinement with each other, and an armature 33 is common to these twosolenoids. T W0 other solenoids 34, 35, are similarlyprovided .With

an armature 36. The armatures'36, 33, are

mounted upon two swinging arms 37, 38, the latter being supported uponleaf springs 39, 40, and loosely connected with the armatures bypins-41.

Mounted within the casing and disposed adjacent to the arm 37 is a lock41 the form of which may be understood from Figs. 6 and'7. This lock isprovided with a slidewa 42 and fitted into this slideway is a sli e 43provided with an opening 44 and with a bevel face 45 partially boundingthis opening. The slide is further provided with a bolt 46 which extendsoutwardly from the lock.

Two spiral springs 47 are mounted within the lock 41 and disposed uponopposite sides of the bolt. These springs engage the slide 43 andnormally press the same toward the left according to Fig. 7 The arm 37carries a pawl 40 for entering the opening 4.4 and engaging the bevelface 45, so that when the arm 37 descends to its limit, the bolt 46 isforced to the right: The arm 37 carries a finger 38 and engaging thislinger is a spring 39 The finger 38 is pivotally supported upon the arm37 and is adapted to swing angularly in one d1rect1on agamst the tensionof the spring 39. 'By this ar-v rangement, the finger 38 is adapted tobend sufiiciently to pass any one of the pins 23 which happens to lie inits path of travel, and when the arm 37 is drawn downwardly .it engagesa pin 23 and thus turns the wheel 22,t0,a distance representing thespace be- -tween consecutive pins 23.

Each time the arm 37 descends so as to cause the movement of the wheel22, as ust mes es described the bolt 46 is thrust outwardly toward theright according to Figs. 6, 7, the pin being thus securel locked betweenthe finger 38 and the b0 t 46. This prevents excessive travel of thewheel 22 and. renders positive the step by step movements of this wheeland parts driven thereby.

Another lock 48 similar in all respects to the lock 41-, is provided, asshown in Fig. 2, and located upon the side of the wheel 22 op osite thelock 41. vi ed with a finger 38 and a those carried by the arm 37 Twoswitch arms 49, 50, constructed'alike, are used in connection with thearms 37 38. The arm 49 is shown more particularly in Fig. 10. It ismounted upon a stationary shaft 51, the latter being supported rigidlyupon the casing. Each switch arm 49, 50, is provided with laterallyextending portions 52 integral with it, and between these laterallyextending portions are the arms 37, 38. Whenever either arm 37, 38, isdepressed, it causes the corresponding switch arm 49 or'50 to rock, andwhen the arm 37 or 38 is moved back into its normal position, the switcharm 49 or 50 is by its aidrestored to normal position. Adjacent thelower end of each switch arm 49, 50, is contact 53, which is normallyopen., but is adapted to be closed by the rocking of the switch arm, asmay be understood from Fig. 10.

Located above each switch arm 49, 50, is a yoke 54 journalecl upon a pin55 and pro vided with a counter-balance 56 for holding the yoke ineither of two extreme positions pawl 48 like into which it inay bemoved, as indicated by dotted and full lines in Fig. 10.

upper end of the switch arm 49 or 50, so that the yoke may be readilyrocked by movements of the switch arm. Each yoke 54 carries a switchblade 59 which is insulated from the body portion of the yoke by meansof insulation 58. Located adjacent each yoke 54 are two contact members(30, (31, so arranged as to be readily engaged or disengaged when theyoke is rocked. switch arm 49,50, carries a" contact button (12, andadjacent to this contact button is a contact spring (33, these partsbeing so arranged that when the switch arm moves into its normalposition the contact button ()2 lodges against the contact spring (33. Alever arm (34 is journalcd upon a shaft 65 and carries two contactmembers 66, (37, and an insulating member 08 for preventing leakage ofcurrent from the contact member. h'ioun'ted adjacent the switch armGel-are con tact sectors (39, 70, which are separated from each other bya sector 71 of insulating nmlerial. Two other contact sectors 712, 73are Each The arm 38 is proprovided and are separated by a sector T-i h 4of insulating material. Located concentrically to thevarious sectorsjust mentioned are two other contact sectors 75, 76, the latter beingalways in engagement with the respective contact members 66, 67. Thelever arm 64 is secured rigidly upon the shaft 65 and is adapted tocause the same to rock. Two other lever arms 77, 78, are journaledloostly upon this shaft and are adapted-to be rocked independently ofmovements of the shaft and also independently of movements of eachother. The lever arm 77 carries a contact member 79, and the lever arm78 carries a similar contact arm 80. Adjacent the contact member 79 aretwo contact sectors 81, 82, separated by a sector 83 of insulatingmaterial.

Adjacent the contact member 80 are two contact sectors 84-, 85,separated by a Sm 86 of insulating material. Connected witthe contactsectors 79, 80 are two armatures I 79, 80 and these armatures extendinto two solenoids 87, 88. 1

The trolley pole carried by the car is shown at 89, the trolley wheel at90 and a portion of the trolley wire at 91. Mounted at each streetintersection is a tripper 92 carried by the trolley wire, and providedwith a laterally extending arm 93, the latter carrying at its outer enda hook 94 extending slightly inward'or toward the wire, as maybe'understood from Fig. 5. The trolley pole 89 'is journaled upon atrolley pedestal 95 carried by the car. This pedestal is provided with alaterally extending arm 96 which carries two contact posts 97, 98, the

latter being supported from the arm 96 byaid of an insulator 99.

Carried by the car and concentric to the trolley pedestal. are contactsectors 100', 101, 102, 103, each having the proximate form of asemicircle. The sectors 100, 101, 102, 103 are insulated by shortsectors 100 of insulating material. Connected with the sector 101 is awire 104. A wire 105 is connected with the sector 103. These two wiresare connected to a wire 106 which leads to the sector 7 53. A-wi're 107is connected to the sector 100. Another wire 108 is similarly connectedto the sector 102. These two wires are connected to a wire 109 whichleads to the sector 76. A wire 110 is connected with the sector 72 andwith a wire 111, the latter leading to the sector 69. The wires 110,111, are connected to a wire 112. A wire 113 ex- .tends from the wire112 to a push button 114 and from the latter wires 115, 116, lead to thesector 81. Connected with the Wires 115, 116, is a wire 117 which leadsto a dis-' tributing post 118. A wire 119 leads from this distributingpost to the trolley pedestal 95. Another wire 120 leads from thedistributing post 118 to the solenoid 87. Connected with the respectivesectors 73, 70, are two wires 121, 122. Connected with these wires 'withthe switch arm 50.

is-a wire 123. This wire is connected with a wire 124, the latter beingin turn connected with a wire leading to the solenoid 35. A wire 126is-connected with the wires 124 and 125, and leads to the pin 51 uponwhich the switch arm 50 is supported. wire 127 leads from the solenoidto the 'giiound 132. A wire 128' is connected with the distributing post118 and also with a wire 129, the latter leading to the solenoid 31.From this solenoid a' wire 1330 leads to the contact member 60,associated with the switch arm 49. A wire 131 leads from the contactmember 61 to the ground 132. By aid of a wire 133 the solenoid 87 is inmetallic communication with the contact 53, the latter being connectedto the ground 132 by a wire 132*. Connected with the wires 112, 113 is awire 134, the latter being in metallic communication'with the solenoid.32. This solenoid is in communication with the ground by a wire 132Connected with the wire 134 is a wire 135 which leads to the pin 51serving as a support for the switch arm 49. Connected with the contactmember 63 is a wire 136 which leads to the sector 82. A wire 137 leadsfrom the distributing post 118 to apush button 138. Connected withthelatter is a wire 139 which is also con-. nected with the wires 123,124. v 95 A wire 140 is connected with the wires 128, 129, and leadstherefrom to the solenoid 3,4. A wire 141 leads from this solenoid tothe contact member-60 associated A wire 142 leads from the contactmember 61, associated with the switch arm 50, to the ground 132. A wire143 extends from the sector 85, to the contact member 63 associated withthe switch arm 50. Connected with the sole- 105 noid 88 is a wire144which leads to the contact'53 associated with the switch arm 50. Fromthis contact a wire 145 leads to the ground 132. A- wire 14? leads fromthe distributing'post 118 to the solenoid 88.110 Another wire 148 leadsfrom the distributing post 118 to the sector 84. Mounted upon theupperend of the trolley pole 89 is a lever 149 and engaging oppositesides ofthis lever are pins 150. Pressing against these 115 pins are springs151, the pins and springs being carried by housings 152 so as tonormally maintain the lever 149 in a predetermined central position, butfree to be moved. slightly in either of two directions when 120 actuatedby a force sufficient to compress either of the springs. The lever 149is (being so positioned as to readily engage the inwardly extendingportion 94 of the trip,

as will be understood from Figs. 4 and 5.

The trolley wheel 90, lever 149 and varilac ous other parts immediatelyassociated with these parts are carried upon a'trolley harpv 155. Twocontact members 105*, 106' are insulated from each other and from thetrolley harp. These contact members preferably have the form of springtongues, as indicated in Fig. 4. These contact members are connectedrespectively to'the wires 107, 108. u,

In Fig. 11-1 show a slightly different arrangement ofthe mechanism. Thecasing appears at 15.6, and the framework at 157. There are'two sprocketchains, one of them appearing at 158. These two s rocket chains eachhave a depending midd e portion 158"engaged by a-sprocketwheel 159.There are two ofthese sprocket wheels which support a roller 160 by aidof a shaft 161. This'shaft extends through vertical slots intheframework, one of them being shown at 162. The purpose of thisarrangement is to enable sprocket chains of different lengths to beemployed, the difierence in lengthbeing compensated by the positionassumed by the roller 160. The weight of this roller rests upon thesprocket chains. By thus having sprocket chains ofdifi'erent lengths,the indicator mechanism may be accommodated to difierences in the numberof street names employed. In other words, the name ribbons may be longor short.

Except as just incucated, the indicator mechanism shown in Fig. 11 islike the indicator mechanism shown in Figs. 1, 2, and 3. The. arm 29 isof proper length to engage ,the switch arm 64 so as to 'SWing thisswitch arm into its reverse position, and the,

arm 28 is of greater length (see' Fig. 1) in order to" engagethe switcharm 7 7 and shift the position of :the latter. Any desired number ofarms 28 may be placed upon the chain 24, though usually a single arm'ofthe kind shown at 29 is suflicient. The chain 25 maysimilarly beprovided with any desired number of the arms 30.

Whcmihe car travels in one direction along the cute, the indicatormechanism is actuated s ep by step in one direction," but .when the carreaches the endoiflthe route, turns around and travels back overthes'ame route, the indicator mechanism travels step by step in thedirection contrary to which it first traveled, the reversal beingbrought about by the action of the arm 29 upon the.

switch arm 64.

The shaft 65 carries a head 88", whereby it may be turned by hand, aswill be understood from Fig.- 1. By turning the shaft switch (shown more\particularly in Fig. 8 can be shifted inde: pendentlyof movement ofthecar. I The operation of my device is as follows:

I willsuppose that the car-is tr veling to the right according to Fig.12, an that the normal direction of travel of the rotary parts of theindicator mechanism is clockwiseaccording to Fig. 2. The contact lever149 is now out of engagement with each of the contact members 105*, 106,and all of the circuits immediately associated with the indicatormechanism are open. The car reaches one of the trippers 92, or in otherwords, arrives at a street, the name of which is to be displayed. Theupwardly extending port-ion 154 of the contact lever now an gages theportion 94 of the tripper so that the contact lever 149 is turnedslightly in a counter-clockwise direction ,according to' back to sourceof supply. This energizes the solenoid 32, causing the switch arm .49 torock in a clockwise direction according to Fig. 12. This rocks the yoke54 in acounter-clockwise direction and causes the contact blade 59 toengage the contact springs 60, 61. This movement of the yoke .54,however, does not take place until the switch arm 49 reaches. the limitof its rocking movement so that the armature 33 reaches its proximatelowest position. The engagement of the contact blade 59 with the contactsprings 60, 61, completes the following circuit: power house, trolleywire 91, trolley wheel 90, trolley pole 89, trolley pedestal 95, wire119, distributingpost 118, -wires 128, 129, solenoid 31, wire 130,contact members 60, 59,61, wire'l31 to ground 132, thence back to powerhouse. solenoid 31, this ste occurring a moment later than that in w ichthe solenoid 32 is energized. The effect of energizing the solenoid 31is to restore the switch arm 49 to'its' normal position, and in so doingto. cause it to rock the yoke 54 so that the contact blade 59 moves outof engagement with the contact members-60, 61. The armature 33 suddenlydescends and immediately rises. This movement causes the arm 38 to dipdownwardly and to returnto its normal position .so that the wheel 22 is'turned one'step in a clockwise direction according to Fig. 2. The shaft21 and parts carried'by it being turned in the same way, the chains 24,25, are actuated and the name ribbon 27 is moved one This energizes thestep-that is, a' distance suflicient to remove alegend from the window14 and display .the next successive, legend-indicating, as

above explained, astreet designation. The

rocking niovementof the switch arm 49 moves the contact member 62 out.of engagement with the contact'inember 63, this.

-movement, however, being virtually idle as the circuit controlled bythese contact incinmenace sented by a tripp'er 92) is reached, the nameribbon is actuated one step. It may happen,

however, that for some reason the operator does not desire a particularstreet name to.

be indicated, whenthe car passes or crosses the street bearing the namein question. In other words, the operator may want the in- (lit-ailingmechanism to skip the name of a particular street when that street isreached. This is accomplished by securing an arm 28 upon the sprocketchain 24 for each street the designation of which is to be skipped. Thelocation of the arm 28 determines the particular street name to be skiped and the number of such arms governs t e number of such names to bethus affected.

I will now suppose that a street of thekind just mentioned is reached bythe car and that such street is duly represented by a tripper 92. Alsothat the arm 28 has been properly positioned, before the beginning ofthe trip, for the purpose of causing the indicator mechanism to make thedesired skip. As the trolleywheel passes the tripper 92., two circuitsthrough the solenoids 31 and 32, are each completed in succession, asabove explained, but the instant the arm 49 is restored to its normalposition, the arm 28 carried by the sprocket chain 24 moves theswitchlever 77 into such position that the contact plate 7 9engages-both or" the adjacent contact sectors 81 and 82. This being donethe restoration of the switch arm 4!) to its normal position causes thecontact member 62 to engage the contact member 63; the result being thatthe following circuit is completed: power house, trolley wire Slittrolley wheel 90, trolley pole 89, pedestal 95, wire 119, distributingpost 118, wires 117, 116,

contact members 81, 7 9., 82, wire 136, contact members 63, 62, switcharm 19,wire 135, solenoid 32, wire 132", to ground 132. thence back topower house. This energizes the solenoid 32 and thus causes the switcharm 49 to 'rock in a clockwise direction so as to actuate the yoke 54,causing the switch blade 59 to engage the contact members 60 and 31 andby so doing complete a circuit through the solenoid 31, as abovedescribed with reference to the action of the yoke fiawhen restoredftoits normal position. It will thus be seen that upon reaching the streetthe designation of which is to be skipped, the solenoids 32, 31., areactuated twice in rapid succession so that the switch arm 49 makes twocomplete movements and is twice in succession restored to normalposition. This means that the sprocket chains and the name ribboncarried by them are all moved two steps in rapid succession. The resultis that the name of the street is displayed for an instant,-the fractionof a sccond.and moved out of the way, another name taking its place andrendered visible through the window 14:.

In practice the momentary display of the name, as described, merelyamounts to the flickering and unintelligible display of the streetdesignation. The pressure of the arm 28 upon the lever 77 for thepurpose of turning this lever is greater than the pull of the armature79 under attraction of'the solenoid 87, so that the momentaryenergizingof the solenoid 87, due to closure of the contact 5 3 by the rocking ofthe switch arm 49, does not prevent the movement of the lever 77 for thepurpose of bringing the contact plates 79 into engagement with thesectors 81, 82, as above described. As soon, however, as the arm 28passes the contact lever 77, after shifting this lever, the solenoid 87restores the lever 77 to its normal position.

This is due to the fact that during the second complete rocking movementof the'contact lever 49, as just described, the contact 53 ismomentarily closed, while the contact plate 79 is still in engagementwith the sec tors 81, 82. The following circuit is thus completed: powerhouse, trolley wire 91,

trolley wheel 90, trolley pole 89, pedestal 95, I

wire 119, distributing post 118, wire 120,:

solenoid 87, wire 133, contact 53, wire 1329,] i;

and ground 132 to power house. This ener l gizes the solenoid 87 andshifts the contact lever 77 back into its normal position.

,. I find it convenient to arrange one or more arms 28 upon the sprocketchain 24:, and

adapt it for use while the car is traveling along the route in onedirection, and to place one or more arms 30, similar to the arm28. uponthe sprocket chain 25 and adapt it use while the car is traveling alongtheroute 5 in the reverse direction. 1

I will now explain how the direction of the step by step movement of theindicator mechanism is reversed when the car reaches the end of theroute and turns around in orcated upon the chain 2 1 that when the car1%.

reaches the end of the route this arm 29 brought againstthe contactlever 64 so as to shift the same in a clockwise direction as;

'. cording to Fig. 12. T In shifting the contact ,7

lever 64, the contact plate 66 disengage the 1M sector 72 and engagesthe'sector 73, its connection with the sector 76, however, beingmaintained. Similarly, the plate 67 disengages. the sector 70 andengages the sector 69, but does not move out of engagement with thesector 75. I will further suppose that the trolley pole89 is not to bereversed relatively to the car-not to be swung around so as to trailbehind. This is usually the case where the car follows a loop around,and therefore virtually travels continuously ahead. In this event, theindicator mechanism must be made to display the street names in thereverse order to that in which they were first displayed. When thetrolley wheel 90 passes a tripper 92, the rocking of the switch arm 149brings this switch arm into engagement with the contact member 105. Thiscompletes the following circuit: power house, trolley wire 91, trolleywheel 90, switch arm 149, contact member 105,

wire 107, contact post 97, sector 102, wires 108*,109, sector 76,contact plate 66, sector 73, wires 121, 12 3, 124, 125, soleniod 35,wire 127 to ground, thence back to power house. This energizes thesolenoid 35, causesthe armature 36 to descend and rocks the switch armin a counterclockwise direction accordingto Fig. 12. This causes theyoke 54 upward, the switch arm 50 being thus rocked back into its normalposition. The performance of the switch arm 50 is exactly like that ofthe switch arm 49 with the exception that the solenoids 35, 34 and 88are energized in.

stead of the solenoids 32, 31 and 87. 'lhe rocking of the switch arm50'causes the-indicating mechanism to display the names of the streets,but in reverse order as above described. Whenever the armfil) carried bythe sprocket chain 25 engages the lever arm 78., so as to shift theposition of. this lever arm, a street designation is practicallyskipped, as above described with reference to the action of the switcharm 77.

If the route of the car does not end in a loop, or if for any reason itis desirable to merelyswing the trolley pole 89 around so as to causethe car to virtually travel backward upon the return trip, the arm 29,used for shifting the position of the switch arm 64, may remain idle.This means that the switch arm 64 is not to be shifted. Under wire 119,distributing post 118, wires 117,.

115, push button 114, wires: 113, 134, solenoid 32, wire 132", ground132, topower house. This energizes the solenoid 32 and causes the switcharm 49 to rock. ing of the switch arm 49 causes the adjacent yoke 54 torock and close a circuit through the contact blade 59, contact members60, 61 and solenoid 31. Similarly, if the car be traveling in thereverse direction, closing the push button 138 energizes the solenoid 35and rocks the. switch arm 50. This rocks the yoke 58, and the contactblade 59 comp letes a circuit through the solenoid 34. he operator,therefore, by pressing, upon either push button 114 or 138, may advanceor set back the name ribbon one'step for each pushof the button.

The operator by grasping the head 88 (gee Fig. 11 can turn the shaft '65so as to s 1ft the switch arm 64 and thus reverse the direction ofrelative movement of the indicator mechanism. With the mechanism shownin Fig. 11, the action is the same as abovedescribed with the exceptionthat the name ribbon may be changed as to its virtual length so as toincrease or diminish the number of streets, the namesof which are 4 tobe displayed.

the spirit of my invention.

I claim I 1.
